This is good, of course! But my hunch is that the primary motive why the parents are sending their children to you to learn about whatever it is you're doing is that they also want them to earn even if they're unemployed.

This is basically all about making money. And this is something every Bitcoin teacher needs to dispel from those who stumbled upon Bitcoin at some point and developed the impression that it is a way to earn quickly and easily. Because that isn't Bitcoin.

So I take exception to your 5^th point. I guess that's incorrect.

Not everyone is necessarily "predicting" it, some are just hoping that a drop would happen so they could buy lower.

Manipulations happen with markets in general. And while manipulation happens with bitcoin as well, it's not as huge of an effect as most people think; especially that as bitcoin's price rise and changes hands, manipulation gets harder and harder.

Depends what you specifically mean with "predict" in this case. Most bitcoiners think, not necessarily "predict" that bitcoin will be priced a lot higher in the future, though they know they can't predict short-term movements.

I have seen information, that most of the trading happens from China by about two huge operators.
